A Wisconsin voter who changes their name has to re-register under the new name. Wisconsin says this is not complete until the new name is on file with the DMV and Social Security first. A voter with a valid Wisconsin license or state ID can then complete the update online.
Do this after your license, not before
Federal motor-voter law puts a voter registration block on most state license applications, so the DMV visit is often the moment a registration is updated too. Whether it actually propagates is a state-by-state answer, and it is the one worth checking rather than assuming — arriving at a polling place under a name the roll does not hold is a problem you cannot fix on the day.
Your registration should match the name you give at the polling place, and it should match the ID you present if Wisconsin asks for one.
